Hacking Full Nand Restore Coming Soon to Hekate Mod

[hippy dave]

Protip: wait for ctcaer's next release and THEN do a full nand backup, because it will have working verification that your backup is correct (his current versions have broken verification - edit: and that's not a sleight on him, no other versions have verification either).

This and then emunand later... I'll be ready baby

Opening with hacdiskmount apparantly verifies that it’s working

Curious if I can restore a bricked switch from a nand backup from another switch on a higher firmware. Would like to use sd card to restore if possible since whenever I run memload and try to connect to pc using emmc it appears then dissapears.

 

[Believ3r]

Will this be useful for those of us who have updated to the latest fw ?

 

[P4wn4g3]

Hey good news.

 

[DutchyDutch]

If you didn't make a backup before doing any crazy shit, is it possible to use someone else's NAND?

Most likely not, while it may be possible one day with editing if you have your keys I believe. I have heard You can replace the part though.

What method would you recommend to do a complete backup?

Hekate has NAND backup tools in the boot menu. I'd recommend using those.

if anyone used sx os V1 the fuses have already been burnt fuse protection wasn't implemented until V1.1

 

[Jayro]

It's about motherfucking time... We still need a way to write the full NAND back to the Wii U, by the way.

I didn't use v1, started on v1.1, so yay!

Question though... Lets say we have made a backup NAND of 5.1.0, and OS v5.2.0 comes out and we update to v5.2.0... will restoring a v5.1.0 NAND backup blow fuses then?

I'm actually really exited for this. I've been holding back on a lot of stuff I've wanted to try because I can't afford another Switch right now.

I doubt this would work without issues.
Each full-raw emmc dump contains console certificates that identify a single machine. Restoring a different devices disk image would cause a hardware serial mismatch. Probably. I am not a switch doctor.

The other day I made a backup using a 32sd card but since my Switch doesn't have the SD update I formatted the SD in fat32. The operation worked I think, it made the backup in about 14 parts. I have to merge them or they're good like this?

You can backup with exFat.
(My firmware 3.0.0)

hekate supports exFAT formatted sd cards, but if you never downloaded the exFAT update, it will not work on horizon os or any homebrew.

 

[Zonark]

This is great news! Now only issue I see is if fuse info gets sent to Nintendo ever. Has anyone done any packet sniffing and found out yet if this info is sent? I don’t think it would be just due to the fact that new systems have less fuses burned

Fuses will only be burnt if you boot up your Switch using their bootloader (i.e. basically turning it on normally). If you boot the Switch using either SX OS v1.2 or Hekate, they will not only bypass the fuse check but prevent fuses from being burnt. This is also why it is recommended to have AutoRCM installed because all it takes is one bootup without RCM for the fuses to be irreversibly burnt. Accidents can and do happen.

I backed up my nand to exfat before manually installing exfat update to horizon on 4.1. I wish there was a walkthrough for this before I started, but it the process was so straightforward. It's these little details that could have been made more clear.

Say you used the method to upgrade without burning fuses (eg going from 1.0.0 to 5.1.0) will this be an alternative to doing it in reverse to undo it? What if you dump the current NAND that you have now, could you go back and forth between them with this?

A reminder that you can load any firmware with Hekate because it bypasses the fuse check entirely, but that defeats the purpose of loading a lower firmware because Hekate needs the Switch to be in RCM. To answer your question, yes.

 

[M7L7NK7]

Yeah just when 1.0.0 gets a coldboot I'll go back down then, will be easier then Rajkosto's way at least
